Not a problem Blue Butterfly, I got some ideas from it myself ^.^ Might try Rini out with some of them and start switching the ones in her cage so she stays interested.
I've given her loo rolls before but I think she eats some of it :/ there never seems to be enough bits left on the floor to make up the roll. I know a little isnt harmful to them so I just limit how often she get one to play with. She seems to enjoy playing with them tho. But I dont give her one that often.

I have a hanging ball that I put hay in. It's above her hay box but she uses it quite abit, and even when it's been empty I've seen her playing with the bell that hangs under it.
